I'm using 64 bit Cygwin.
I guess that the "compilation finished" message I got is because of my
compiling interface, so I don't think is important.
Regarding the checks you suggested:

$ cygcheck gfortran
Found: D:\Cygwin64\bin\gfortran.exe
Found: D:\Cygwin64\bin\gfortran.exe
Found: D:\Cygwin64\bin\gfortran.exe
D:\Cygwin64\bin\gfortran.exe

And then a bunch of dll's. When I check gfortran I get

$ which -a gfortran
/usr/bin/gfortran
/usr/bin/gfortran
/usr/bin/gfortran

While for blas:

$ which -a cygblas-0.dll
/usr/lib/lapack/cygblas-0.dll

Thanks!
